Birth Chart Calculator
Enter your birth details to instantly calculate your natal chart — your Sun, Moon, Rising sign, and planetary positions.
What is a birth chart?
A birth chart (also called a natal chart) is a snapshot of the sky at the exact moment and location you were born. It maps the positions of the Sun, Moon, and planets across the twelve astrological signs and houses, revealing a blueprint of your personality, strengths, challenges, and life path.
How accurate is this calculator?
Our calculator delivers professional-grade accuracy for planetary positions. For the most precise Rising sign and house placements, provide your exact birth time — the Ascendant changes every two hours, so even a small difference matters.
What if I don't know my birth time?
You can still get meaningful results without your birth time — your Sun sign, Moon sign, and most planetary placements will be accurate. The Rising sign and house placements require your birth time for precision, as the Ascendant moves through all 12 signs over 24 hours.
